The number of patients in the denominator who have
all the elements of demographics (or a specific
exclusion if the patient declined to provide one or more
elements or if recording an element is contrary to state
law) recorded as structured data.
Number of unique patients seen by the EP or admitted
to an eligible hospital’s or CAH’s inpatient or
emergency departments (POS 21 or 23) during the
EHR reporting period. A unique patient is discussed
under the objective of CPOE.
The resulting percentage must be more than 50 percent
in order for an EP, eligible hospital or CAH to meet this
measure. Most EPs and all eligible hospitals and CAHs
would have access to this information through direct
patient access. Some EPs without direct patient access
would have this information communicated as part of
the referral from the EP who identified the service as
needed by the patient. Therefore, we did not include an
exclusion for this objective and associated measure.
Numerator: The number of patients in the denominator
who have at least one entry or an indication that no
problems are known for the patient recorded as
structured data in their
problem list.
Denominator: Number of unique patients seen by the
EP or admitted to an eligible hospital’s or CAH’s
inpatient or emergency department (POS 21 or 23)
during the EHR reporting period.
Threshold: The resulting percentage must be more than There are no exclusions for this objective and its
80 percent in order for an EP, eligible hospital, or CAH associated measure
to meet this measure. We do not believe that any EP,
eligible hospital, or CAH would be in a situation where
they would not need to know at least one active
diagnosis for a patient they are seeing or admitting to
their hospital. Therefore, there are no exclusions for this
objective and its associated measure.

medication (or an indication that the patient is not
currently prescribed any medication) recorded as

maintaining an up-to-date problem list.
The number of unique patients in the denominator who
have at least one entry (or an indication that the patient
has no known medication allergies) recorded as
structured data in their medication allergy list
Number of unique patients seen by the EP or admitted
to an eligible hospital’s or CAH’s inpatient or
emergency departments (POS 21 or 23) during the
EHR reporting period. The definition of “a unique
